If you’re a fan of retro Apple products, your classic computers are only going to have so much functionality today. But what if you could somehow take the guts of a modern Mac and use it to power an old-school Mac from the 80s? Such a project would require a transplant of Frankenstinian proportians.

You won’t hear about it at any upcoming Apple events, but there’s an entire subculture of Apple fans who are devoted to hacking Apple hardware. You may be familiar with the Hackintosh phenomenon, which involves installing OS X on non-Apple PCs.

What you may not have heard of is the Hackintosh’s distant cousin, the Frankintosh. As the name suggests, it transplants two Apple products in ways that are positively unnatural. The latest Frankintosh combines two distant generations of Apple computers into an amalgamated contraption that would make Mary Shelley proud. Meet the G4 Apple IIc.

This beauty has the body of a 1984 Apple IIc, but the mind of a Mac Mini G4 (pre-Intel). This is no half-hearted effort either. The original keyboard and mouse (remember those boxy things?) work perfectly, as they’ve been spliced to connect via USB with the Mac Mini.

Perhaps the sweetest part is that the monitor has the same green and black monochrome display that it did in the mid-80s — only it’s running OS X 10.4 Tiger. The Mac Mini supplies it with a 1.4GHz processor and 1GB of RAM. That’s quite the upgrade over the 1MHz microprocessor and 128KB of RAM that this IIc originally sported.
